La temperatura de transicion vitrea (Tg) de un material es el rango de temperaturas donde ocurre la transicion entre un estado cauchoso y un estado vitreo, produciendose cambios que se ven reflejados en sus propiedades fisicoquimicas. El objetivo de este trabajo es determinar las curvas de transicion vitrea (Tg vs. Humedad de grano) de tres variedades uruguayas de arroz y evaluar si existen diferencias significativas entre ellas. Se estudia tambien la influencia de la humedad de cosecha (HC). Para ello, cada muestra de arroz se seca por diferentes periodos de tiempo para obtener humedades de grano (HG) en un rango entre 10% y 22% (en base humeda). A continuacion, se mide la Tg por calorimetria diferencial de barrido (DSC). Los resultados se comparan aplicando ANOVA y el test de Tukey. Se observo que la Tg aumenta a medida que disminuye la HG para las tres variedades estudiadas. Las curvas de transicion vitrea muestran que existen diferencias significativas entre las tres variedades en el rango de HG de 12% a 16%. La HC no afecto la Tg en todo el rango estudiado. Los resultados obtenidos pueden aplicarse para optimizar el proceso de secado del arroz, minimizando la formacion de fisuras.

The golden mussel (Limnoperna fortunei) is an invasive exotic species that has several negative impacts in ecosystems worldwide. Santa Lucia River is the main drinking water source, supplying 60% of the total population of Uruguay. L. fortunei has been reported since 1996 in the basin, and nowadays is present in the three reservoirs that supply the water treatment plant. The aim of this study was to analyze the temporal dynamics of L. fortunei larvae in Aguas Corrientes reservoir (Santa Lucia River). We quantify diary L. fortunei larvae and phytoplankton, we also measure physicochemical parameters of water. L. fortunei larvae showed a seasonal dynamic and its development was promoted by temperatures up to 17°C. Temperature was the main variable controlling the presence of larvae. Once temperature was optimal for its reproduction, the reservoir level was the key variable to determine the presence of larvae. This shows the importance of flow managing in the reservoir in order to reduce golden mussel impacts during the reproductive season. We also propose two alternative regulation mechanisms of larvae, acting at two different scales: physiological and environmental.

Continuous measurements of environmental conditions in coastal zones are key to understanding oceanographic and atmospheric processes, as well as improving our understanding of the marine environment for operational and conservation purposes that can be integrated into a marine spatial planning process. Several efforts have been made in Uruguay in order to achieve these goals, but they have not sustained over time due to high operative and maintenance costs of specific sensors. This work presents the first results of more than a year of continuous measurements of temperature and salinity in the Rio de la Plata obtained using a low cost solution and through a high-commitment multi-institutional teamwork between the academy and state agencies. Measurements were obtained with a DST-CTD sensor installed in Flores Island National Park, a key sampling point for the external zone of Rio de la Plata. The relevance of having this type of information is presented and the need for the implementation of a continuous long-term monitoring system is discussed.
对沿海地区环境条件的持续测量是了解海洋学和大气过程的关键，也是提高我们对海洋环境的理解，以实现可纳入海洋空间规划过程的业务和保护目的的关键。乌拉圭为实现这些目标作出了若干努力，但由于特定传感器的操作和维护费用高，这些努力未能长期持续下去。这项工作展示了在一年多的时间里，通过学院和国家机构之间的高承诺多机构团队合作，使用低成本的解决方案获得的里约热内卢de la Plata温度和盐度连续测量的第一批结果。使用安装在弗洛雷斯岛国家公园的DST-CTD传感器进行测量，该公园是里约热内卢de la Plata外部区域的关键采样点。提出了获得这类资料的重要性，并讨论了执行一个连续的长期监测系统的必要性。

In the quantity of volume, gravimetric method is considered the best accuracy method for the quantitative determination of an analyte based on its mass. The distilled water is selected as calibration liquid because it is well known how its density changes with temperature. For volume calculation at reference temperature, the water density value is obtained by known mathematic models, for example, Tanaka equation (Tanaka, et al., 2001). According to ISO 3696 (International Organization for Standardization, 1987), there are requirements for water (Grade 3), the lab needs to perform periodic studies of conductivity, but it is necessary to study the water density deviation and comparing this value with that obtained by Tanaka equation. If this deviation value (calculated by Tanaka Equation vs Oscillation – type density meter is significant, it must be considered in the uncertainty estimation for volume calibration using gravimetric method.
在体积的数量上，重量法被认为是根据分析物的质量进行定量测定的最准确的方法。选择蒸馏水作为校准液，因为众所周知，蒸馏水的密度随温度的变化是怎样的。对于参考温度下的体积计算，水密度值由已知的数学模型获得，例如Tanaka方程(Tanaka, et al.， 2001)。根据ISO 3696(国际标准化组织，1987)，对水(3级)有要求，实验室需要进行电导率的定期研究，但有必要研究水密度偏差，并将该值与田中方程得到的值进行比较。如果该偏差值(由田中方程与振荡式密度计计算)显著，则在用重量法进行体积校准的不确定度估计时必须考虑该偏差值。

Biopolymers are useful in the industry due to its elastic properties and sustainability as replacements of non-renewable polymers. In this article, bioplastics were produced and characterized using chitosan (CH), sodium alginate (SA), and galactomannan (GAL) from insects (Hermetia illucens), brown algae (Macrocystis pyrifera) and seeds (Leucaena leucocephala), respectively. The structure of biopolymers was observed by infrared spectroscopy (FTIR) and characterized by viscosity at different concentrations. The developed bioplastics were characterized by color and mechanical properties (texture). The results were compared to standard samples (commercial). The FTIR spectra confrmed the presence of the typical structure (footprint) for the obtained polymers. The SA showed signifcantly higher viscosity for all concentrations comparedto the standard and the other polymers. The bioplastics strength was similar among CH, SA and GAL for all concentrations; only SA (0,5%) demonstrated higher strength than the standard. For color measurements, hue value indicated a red-yellowish color and the chrome increased directly proportional with polymer concentration. The observed properties suggest that these sustainable sources might be an alternativeto bioplastic production, which can be extended to functionalization and molecular interactions for broad applications in different industries.

The main objective of the present work is to help combat food waste, which is one of the main problems of the food industry today, incorporating also sustainability concepts. According to the FDA each year about 1,300 million tons of food are thrown. Food is wasted mainly at household levels, which is why the choice of the sustainable design of an intelligent interconnected packaging for domestic use is made. To achieve this, the exploration of different technologies, materials, methodologies and innovative frameworks is carried out. Regarding materials, the possibility of using biodegradable, recycled, recyclable and bioplastics was studied, along with the research of the intelligent technology to use, which ended up being sensors. As to methodologies, Life Cycle Analysis (LCA) and Cradle to Cradle philosophy (C2C) are deeply studied. Intelligent packaging systems are an option to contribute to minimization of food waste. The correct use of tools such as the LCA, along with the principles of the C2C, and the research on materials and technologies to be used can help designers to reach an optimal solution, minimizing environmental impacts.

During the industrial production of pomegranate juice, peel is generated as a by-product. The aim of this work was to valuate this by-product through the green extraction of soluble antioxidants while recovering insoluble fiber. Pomegranate by-product once dried and ground was subjected to a water extraction process (65 °C for 30 min), obtaining two fractions: soluble and insoluble ones. The insoluble fraction had a high fiber content (52,28 ± 2,99 g/100g) while the soluble fraction had a high total polyphenol content (1049,98 ± 3,98 mg gallic acid/100g) and an antioxidant capacity against ABTS radicals of 1486,57 ± 0,05 μmol Trolox/g. Using the soluble fraction, a jelly and a beverage were formulated, while cookies and muffins were formulated with the insoluble fraction. All products were formulated without sugar, and cookies and muffins also complying with the claim “source of fiber”. Acceptability was evaluated by consumers (n = 100), being cookies and muffins the most accepted (7,0 and 6,3, respectively). Pomegranate by-product was revalued in a sustainable and low cost way, obtaining new functional ingredients, so representing an opportunity for industry.
